This animation is made with points in a Python
collections.dequedata structure, added by dragging the mouse (code bellow).
from collections import deque # a double-ended queue
import py5 # check out https://github.com/py5coding
history = deque(maxlen=512) # mouse dragged positions
def setup(): # py5 will call this once to set things up
py5.size(600, 400)
py5.no_stroke()
py5.color_mode(py5.HSB)
def draw(): # py5 will call this in a loop
py5.background(51)
for i, (x, y) in enumerate(history):
py5.fill(i / 2, 255, 255, 128)
py5.circle(x, y, 8 + i / 16)
history.rotate(-1) # Thank you Ramalho! Previously `if h: h.append(h.popleft())`
def mouse_dragged(): # py5 will call this when you drag the mouse
history.append((py5.mouse_x, py5.mouse_y))
def key_pressed(): # py5 will call this when a key is pressed
history.clear()
py5.run_sketch()- 💬 Ask me about drawing with Python!
- Check out py5 and my modified pyp5js hack, they bring in the vocabulary from Processing & P5js!
- I try to make a new drawing with code everyday, and I put the results at skech-a-day.
- 🔭 I have just finished a PhD at Unicamp by the end of 2025. I have very little idea of what I'm going to do now...
- 👯 I’d like to collaborate on open resources to teach programming.
- I collect tools for teaching Python with visual results here.
